So after years of working out to various levels of intensity and having been a variety of different levels of physical fitness and development (seriously I've been everything from stick thin, to pretty muscly, to tub of lard, to just average and all of them multiple times) I have done lots and lots of different kinds of upper body exercises and used a lot of equipment. But throughout all this one fact has remained the same, my upper body is marginally asymmetrical. I know this is fairly common, and in most cases it isn't all that pronounced, but in my case it's always been slightly more pronounced than I'd like, though not enough that anyone else has ever really noticed. I'm back to working out fairly regularly again now, and I suppose this is a question for our hardened gym goers and fitness aficionados, but how do I counter and rectify this asymmetry? My right arm is larger than my left arm, and is much stronger (not uncommon I know, but I have a feeling this is more than average), and my left pec is larger and stronger and better developed than my right one. I get the feeling that my right arm compensates for the weakness of the right pec, and the left pec compensates for the weakness of the left arm, hence the disparity. I've done targeted exercises like pressups on one arm, free weights routines, increasing numbers of reps to work the less developed muscle groups etc etc which claim to help with this, they haven't been very successful, but does anyone have any tips and tricks I could use to try to remedy this, or am I stuck with what nature gave me?
